The biggest difference between Pete and Hunter is that Hunter is working a program aimed at helping him live "one Day at a Time," as a clean and sober person, Pete appears to still deny his underlying problem. Someone, close to Pete, should invite him to a meeting. He will not be able to find true happiness, no matter how many Generals he fires, as long as he remains in denial. Stop enabling him. There are many Trump allies who could replace him as the nominee.
I don't hate anyone. I have hated less than a handful of people and the last one died last year. As a leader, I liberated myself from hatred decades ago. I found it helpful to keep my mind open to the ideas of subordinates. Hating, even strongly disliking people closes things up unnecessarily. Hate is an expensive-learned behavior I choose to not buy.
Although hate appears to be a cornerstone principle of MAGA and similar philosophies, you can choose to let it go. I suspect that your load will be lighter, if you do so.
